What the filename identifies
The A_MOD-2195 suffix distinguishes this file from the base catalog entry. The MOD label indicates a modified variant, but it does not identify the changes made to the calibration. The filename alone does not establish a specific vehicle application or describe a change in engine behavior.
An engine control module uses calibration data to govern functions such as fuel delivery and ignition timing. Those are general controller functions, not confirmed changes in 89663-35450-A_MOD-2195.bin.
